An 80-year-old man was violently attacked in an unprovoked incident in Old Trafford at the end of last month.
The incident happened on July 29 2012 shortly before 10.55am, when the man was in his car, a blue Vauxhall Astra, at the junction of Kings Road and Upper Chorlton Road.
A man approached the car, opened the door and then began to kick and punch the elderly man in his face and head as he sat inside his vehicle.
The man then walked off along Kings Road, away from Upper Chorlton Road.
The victim suffered facial injuries and was taken to hospital for treatment.
Police are hunting the offender who is described as mixed race, Afro-Caribbean, with short black hair.
He is believed to be in his late 20s, of medium to heavy build, and was wearing a brown or grey hoody.
Detective Inspector Debbie Oakes from Stretford CID said, "I would appeal to anyone who may have seen this incident to come forward and speak to the police.
“This was a vicious and completely unprovoked attack on an elderly man who needed hospital treatment for his injuries.
"We have released CCTV footage of a man we would like to speak to in connection with this attack and I would encourage anyone who thinks they may recognise this person to contact officers at Stretford CID.
"On the day this attack happened, Egypt were playing New Zealand in the Olympics at Old Trafford football ground, which may help to jog people’s memories and help them to remember what they were doing.
“We do not believe the attack was in any way related to the football.
"We are determined to identify the individual responsible and ensure he is made to pay for his what he has done."
